HCM beads control humidity by establishing an equilibrium in your humidor's closed
environment. The beads are preset to 65% RH and are designed to maintain equilibrium. The key point here is that
your humidor must seal well (i.e., be a closed environment).

If your humidor leaks, all is not lost! There are things you can do with weather-stripping, silicone caulking,
and other materials to seal your humidor. If your humidor is air-tight then you are good to go, and the beads will
keep your RH at a rock-solid 65%!

The Beginning

Scott Shilala invented the HCM beads over a period of months and began selling them in late 2008. Since their
inception the HCM beads have proven to be a big hit with cigar enthusiasts.

How Much Do You Need?

Generally you use 8 oz of HCM beads per 2.5 cubic feed of humidor volume. Most people use double this amount to be safe.
